In practice, ordinal data is sometimes converted into a numerical format and treated like quantitative data for the sake of convenience. The mean cannot be calculated for ordinal data, so the median can’t be found for an even-numbered dataset.įor example, if the two middle values are “slow” and “medium,” you can’t calculate the mean of these values. Can you find the median for an even-numbered ordinal dataset? The median is the value at the 4th position. Next, find the middle value using, where n is the number of values in the dataset. You categorize reaction times of participants into 3 groups: slow, medium or fast.įirst, order all values in ascending order. We’ll walk through the steps for an odd-numbered ordinal dataset with 7 values. The process for finding the median is almost the same. Ordinal data is organized into categories with a rank order – for example language ability level (beginner, intermediate, or fluent) or level of agreement (strongly agree, agree, etc.). But you can sometimes also identify the median for ordinal data. The median is usually used for quantitative data, which means the values in the dataset are numerical. The median weekly pay for this dataset is is 425 US dollars. To find the median, calculate the mean by adding together the middle values and dividing them by two. Step 4: Find the mean of the two middle values. The middle values are at the 3rd and 4th positions. The middle positions are found using the formulas and, where n is the number of values in your dataset. Step 2: Calculate the two middle positions. Step 1: Order the values from low to high. In an even-numbered dataset, there isn’t a single value in the middle of the dataset, so we have to follow a slightly different procedure.
